The latest weekly boss fight is only unlocked after you complete Act 5 of the Archon Quest, Incandescent Ode of Resurrection. You will initially fight this enemy during the mission, but its domain won't appear on the map until you complete the quest as it is tied to key moments of the story.

After you've completed the quest, you will be able to find a new Trounce Domain called Stone Stele Records located in the Tezcatepetonco Range area of Natlan. This part of the map was introduced in the 5.2 update of the game. Teleport to the location and you will be able to access the Lord of Eroded Primal Fire boss in Genshin Impact.

Keep in mind that this domain will only appear once you have completed the fifth Act of Natlan's Archon Quest and not right after you have defeated the boss in the story. You will be able to challenge the Lord of Eroded Primal Fire boss and receive drops from the domain once every week. Completing the challenge and claiming its rewards will reward you with the following drops:

• Eroded Horn
• Eroded Sunfire
• Eroded Scale-Feather
• Artifacts (3 - 5-star rarities)
• Dream Solvent
• Agnidus Agates
• Borderland Sword Billet
• Borderland Claymore Billet
• Borderland Bow Billet
• Borderland Catalyst Billet
• Borderland Polearm Billet

If you have obtained Mavuika in Genshin Impact, you will be able to use the Eroded Horn to upgrade her Talent levels.
